<p>An object of the present invention is to enable a communication terminal apparatus that does not support high-speed signals to correctly extract clock from a received signal in a network in which a low-speed signal and a high-speed signal having the speed of an integer multiple of the speed of the low-speed signal are time-division multiplexed and transmitted. To achieve the object, an OLT (100b) that functions as a communication apparatus includes a pulse generating unit (130b) that generates repetitive pulses having the same width as the low-speed signal and a pulse superimposing unit (140b) that superimposes the pulses generated by the pulse generating unit (130b) on the high-speed signal so that the low-speed clock can be extracted.</p> |
